Abstract
An arrangement and method for update of configuration cache data in a disk storage subsystem in which a cache memory () is updated using two-phase () commit technique. This provides the advantage that known changes to the subsystem do not require an invalidate/rebuild style operation on the cache. This is especially important where a change will invalidate the entire cache.
